Google MindReader

So AdSense kicked in on the blog... and at least half the ads I'm seeing are for Disney World related services. Now that seems like a perfectly logical thing to advertise on my blog, given how Disney World crazy I am, but... how does AdSense know?! Prior to this post, nothing on the blog mentioned Disney World. Is Google reading my mind? Well I suppose, being Google, it's more likely to be reading my search history... but it was still unexpected and somewhat creepy...
